9. Does the equation y = 2x represent

a linear or a nonlinear function?

Answer: Liner

Step-by-step explanation: All liner equations are written in y = mx + b. or (y - y1) = m (x - x1) and your equation is written in y=mx+b but your equation would start at the orgin on a graph since it does not have a b value

linear

Step-by-step explanation:

So, the slope is constant, meaning the graph is a straight line.

So, it is linear.
